Abstract
The work investigated the physical, mechanical and sorption properties of cellulose-containing wastes of agro-industrial production, formed as a result of manufacturing activities of one of the large agricultural enterprises in the Republic of Tatarstan. To improve the sorption properties, the wastes were chemically modified via treating them with sodium hydroxide solutions with 0.5, 1, and 3% concentrations at a temperature of (20 ± 2) ° C. Standard and operating diesel oils were used as sorbates. As a result of alkaline treatment, there is an increase in the maximum oil absorption of sorption materials in relation to engine oils, an increase in the sorption activity with respect to iodine, which characterizes the material porosity, as well as a decrease in the bulk density of the modified samples. The best physical, mechanical and sorption properties were found in cellulose-containing waste treated with a 3% sodium hydroxide solution.
